WILLIAM PRINCE-SMITH AND DAVID WATERHOUSE, OF .KEIGHLEY, ENGLAND.

SfIINNING, TVVISTIN'G, AND ANALOGOUS MACHINE.

Application filed September T all whom it may concern:

Be it known that we, WILLIAM PRINCE- SMrrrr and DAVID lVATEm-roUsn, both subjects of the King of Great Britain, residing at Keighley, in the county of Yorkshire, England, have invented certain new and useful In'iprovements in Spinning, Twisting, and Analogous Machines, of which the 3 port from bearings carried by a vertically movable rail.

The invention has for its principal object to enable the dofling operation to be performed in a more simple manner and in fewer movements than heretofore; other objects being to obviate inconvenience and" loss of time due to the drag washers becoming displaced as occurs frequently with machines employing a single lifter-rail, and also to enable any drag washers which require renewal to be replaced with facility while .the machine is in operation and without stopping or interfering with any functioning part for that purpose.

Accordingly the invention comprises a spinning, twisting or analogous machine having live spindles on to and from which the bobbins are transferred, by the manipulation of two separate apertured lifter-rails alternately, from and on to bobbin pegs capable of being aligned co-axially with the spindles; the bobbins resting on their respective drag washers throughout their transference.

Suitable means are provided for displacing and positioning the various movable parts or members, and appropriate devices are included on the machine for the purpose of severing the yarns or threads after the full bobbins have been doffed on to their respective bobbin pegs.

A flyer-spinning frame, by way ofexample, may be constructed according to the present invention in the following man- 1161 i I Live spindles supported by an overhead 3, 1924:. Serial No. 735,637.

rail are driven by whorls carried above the flyers which rotate as one with said spindles, and the lower endsof said spindles are received for lateral support in appropriate bearings borne by a continuous rail adapted to be displaced vertically during dofiing by rack pillars and pinions, or otherwise suitably.

Two separate lifter-railsare provided, exchangeable with each other and each in turn functioning periodically to traverse in the usual manner the bobbins receiving the yarn or thread during the spinning operation; each of these lifter-rails being formed with a series of apertures corresponding to the number and positions of the spindles which can pass freely therethrough.

The usual pokers operated by known or appropriate mechanism serve to travel that lifter-rail for the time being positioning bobbins for the spinning operation.

Two transfer rails are also provided, each of which carries a series of short upstanding bobbin pegs of a diameter and position corresponding with the diameters of the spindles, these transfer rails beingfurnished with appropriate mechanism for manipulating the respective series of bobbin pegs into axial alignment with the spindles in order to receive therefrom or to place thereon full or empty bobbins as the case may be.

Each of said transfer rails co-acts with one of the aforesaid lifter-rails when the exchange of bobbins -is required to take place.

Appropriate threadsevering means are provided, as well as other accessories usual in machines of this kind.

In the accompanying drawings, which illustrate one practical example, Figures '1 to 6 inclusive .show a vertical sectional elevation of one side of a flyer spinning frame; in Figure 1 the parts being in the spinning position, while in Figures 2, 3, and 4, the successive positions occupied by the parts during the dotting operation are indicated. In Figures 5 and 6 two positions taken up subsequently to the dofling operation are illustrated.

Figure 7 is a front elevation of the left hand end of the machine, and Figure 8is a sectional plan view thereof.

1 is the end stand of the main frame of the machine, l is an intermediate frame member and 2 is a rail secured longitudinally of the machine upon brackets 3,

which rail supports in known manner a series of depending live spindles 1 carrying flyers 5 and driving whorls 6.

7 is a. vertically movable rail disposed longitudinally of the frame and having b ushed apertures or carrying bearings .to receive and afford lateral support to the lower ends of the spindles 1 as .is usual in this type of machine. This rail 7 is carried by a number-of vertically movable rack pillars 8 operated by pinions 8 mounted upon a horizontal shaft 8 9 and 10 are the two hatter-trails, the rail 9 being shown carried at the heads of the usual pokers 11 and the rail 10 being located dor the time being upon :a .transa' er peg or pin-rail 12 which together with another similar transfer peg or pin-rail 13 parallel to it is supported by cranked bracket-s 14 carried in front of the spindles by horizontally movable rack rods 15 operated by pinions 15 mounted upon a shaft 15.

F are the full bobbins, E are the empty bobbins, and f zand e are their respective drag washers.

The transfer rails 12 sand 1 3 are each pro vided -wi th a series :of aipstanding .short pegs or pins 16 .and 17, respectively, which correspond in number, diameter and position with the spindles 4:; (and the lifter-rails 9 and 10 are each fashioned with a-series of apertures spaced correspondingly with the spacing of the pins 16 .and 17 and of a size to permit the litter-rails to pass freely over the spinning :spinidles or on to the pins 16 .and 17 as the case may be.

The rails 9., 10, 12 and 13 are not-continuous but are divided into lengths appropriate to groups of spindles, the elements; of the rails 9 .and 10 be'ingisliiglrtly larger than ihose of the rails 12 and 13 the ends; of which rails '9 and 10 overlap sufficiently to enable them to be engaged by the pokers, as will be clearly seen on reference .tov Figures 7 and .8.

18 is a slidably movable rod arranged longitudinally of the machine in rear of the fiyers 5-.and carrying a series of projecting pins 19 that arcadapted .to be engaged with the .fiy-ers 5 to align or straighten them in the Well known manner prior to the dolling operation.

20 is an angularly movable rod disposed longitudinally of the machine in rear of the spindles :and carrying a series of pairs of Wire prongs or fenders 21 springing from sleeves 22 rotatable with rod 2O; said prongs or fenders 21 serving to hold the yarn or thread clear of .the spindles and to prevent it from wrapping or coiling round them during dotting as it would otherwise tend to do.

23 is a sliding cutter bar of usual form rfor severing .the yarns or threads and is carried by brackets 24 supported at the heads of rack pillars 25 slidable vertically in guides 26 carried by a fixed rail 27 and operated by pinions 25 mounted upon a horizontal shaft 25*. The brackets 2% are each formed integrally with a forwardly projecting platform 28 adapted to be used to transfer a lifter rail after its removal from the spindles as explained hereafter.

The above described apparatus operates in the following manner.

Assuming that all the parts are in the spinning position shown in Figure 1 and that the series of bobbins F have: just -be-- .come filled with the correct amount of thread, the fiyers 5 are first of all straighterred in the well-known manner by sliding the rod 18 and engaging the pins 1:9 carried thereby with the fiyers so as to position them in a. plane parallel with the nnichine.

The rail 7 is then lowered by turning shaft 8 and when it has reached the bottom of its travel the shaft '15 is operated soas to cause rack rods 15 to move the cranked brackets 14: into .such position that the pegs 17 carried by transfer will 13 :are in :axial :ali nment below the ends of the spindles 4-.

Then, by operating the usual lifter moion in the ordinary manner the pokers 11 and with them the lifter-rail 9 carrying the full bobbins F are lowered, at the saane time the 1 0-Cl. 22 is moved angidarly ward so as to cause the prongs 21 to in-ts"- ccpt the threads extending between the eyes of the flyers 5 and the full bobbins I? as the latter descend with the lifter-rail 9; :the threads as they u-ncoi-l from the bobbins being by this means prevented from don ing :the spindles by becoming wrapped ir and :them. The lifter motion is operated until the lifter-rail :9 with the fbobbi'ns F have passed over the pegs 1.7 and rest on .the transfer rai-l The rack rods 15 are then operated soas tomove the cranked brackets 14: forwardly until the pegs 16 carrying the empty bobbins E are in axial alignment below the spindles l, that is to .say, into the position shown in Figure 3, after w h, by once more actuating the lifter mo n, the pol;- ers 11 are raised and, taking under the duplicate lifter-rail 10, raise it and the empty bobbins E on to the spindles ll. At .the same time-the rod 20 .is moved angularly backwards so .as to raise the prongs 21 once more into the vertical or inoperative position.

It will be iobserved -that during these movements the full bobbins F, and empty bobbins E have remained undisturbed upon their respective :drag washers .and re.

The rack-rods 15 are now operated .tomove the cranked brackets 14 still further forward, into :the position shown in Figure lifted clear of the tips of the pegs 16 and 25 are then lowered until the cutterbar has resumed the lowermost position of rest' and the doffing being now completed spin ning is recommenced.

It'now' remains to dispose of the full bobbins F and to position the lifter-rail 9 with the drag washers f thereon in readiness to receive a series of empty bobbins for use when the next doffing period arrives.

To this end, at any convenient time dur ing the spinning operation, the full bobbins F are removed by hand from the transfer pegs 17 and when all have been collected therefrom the rack-rods 15 are manipulated until the lifter-rail 9* is positioned above the platforms 28 whereupon the rack-pillars 25* are raised until the lifter-rail 9 has been 17, as shown in Figure 5, upon which the rack-rods 15 are again moved to bring forward the series of pegs 16 and when theseare axially below the apertures in the lifterrail 9 the rack-pillars 25 are lowered and the platforms 28 deposit the lifter-rail 9 upon the transfer rail 12, as shown in Figure 6, after which the brackets 24 are lowered to their position of rest carrying the platforms 28 clear of the rail 12, as seen in Figure 6. A fresh series of empty bobbins is then placed by hand upon the transfer pegs or pins 16, and the apparatus is completely prepared for the next doffing operation when necessary. 7

Instead of bemg suspended from the overhead rail 2 the spindles 4: may be so ar- Y ranged as to have vertical support by means offootstep bearings carried by the rail- 7, the upper ends of the spindles receiving lateral support from the rail 2 and means being provided to hold and retain the spindles vertically when the rail 7 is lowered during dofiing. One simple arrangement by which the spindles 4 can be thus temporarily supported is to fit on or form each spindle with an annular collar and to attach to the overhead rail 2 adjacent to the upper end of each spindle a suitably shaped stop" or bracket on to which said annular collar would be brought when the vertical support of the spindle rail 7 is removed from the lower ends of the spindles. During spinning these annular collars would be just out brackets and would come to rest thereon as the result of slight downward movement of the spindles on the withdrawal of the spindle rail. No Variations or alterations are necessitated in the construction or functioning of the actual dofiing mechanism under such circumstances.
